Abstract :
A low-loss quasi-optical Ka-band polarization rotator array with 18% bandwidth has been designed and tested. Each cell of the array consists of a pair of input probe antennas connected via microstrip lines to orthogonally oriented output probe antennas. The design shows promise for use as an active array, as multistage MMIC amplifiers can be inserted in a straightforward manner into each cell.<>
